| gal/h | Gallon/Hour (US) | 951.02235 |
Formula: gal/h = L/s × 951
Multiply any L/s value by 951 to get gal/h.
Reverse: L/s = gal/h × 0.001052

1 L/s = 951 gal/h.
m³/s × 1000 = L/s × 60 = L/min. Use this chain for quick conversions.
Multiply result by 0.001052 to recover the original L/s value.
Designs pumps, pipes, and water distribution systems with flow rates in m³/s, L/s, and GPM.
Specifies air handling units and ductwork in CFM (ft³/min) and m³/h for North American and European projects.
Monitors and controls treatment processes with flow rates in m³/h, L/s, and MGD.
Designs sprinkler systems with required flows in GPM and L/min per NFPA standards.
Measures river and groundwater flows in m³/s (m) and ft³/s (cfs) for flood modeling and water resource planning.
Configures ventilators and oxygen delivery systems with flow rates specified in L/min.
Liters per second (L/s) is widely used in water supply engineering, fire protection, and irrigation where liter-scale flows are practical. One L/s = 0.001 m³/s = 60 L/min.
Fire hoses typically deliver 7–25 L/s. Municipal water distribution systems are designed for flows in L/s. Swimming pool filtration systems run at 1–10 L/s. A garden hose delivers about 0.3 L/s.
Interesting fact: The human heart pumps about 0.083 L/s (5 L/min) at rest, rising to 0.333–0.5 L/s (20–30 L/min) during intense exercise. Over a lifetime, the heart pumps approximately 200 million liters of blood.
Gallons per hour (gal/h) is used for slower flow rates such as fuel consumption, slow drip irrigation, and residential water softeners. One gal/h = 1.0514 × 10⁻⁶ m³/s ≈ 0.0631 L/min.
Vehicle fuel consumption at highway speeds is typically 2–8 gal/h for gasoline engines. Water softeners regenerate at 0.5–2 gal/h. Fuel oil burners for home heating consume 0.7–3 gal/h depending on output.
Interesting fact: A dripping faucet (one drip per second) wastes about 3,000 gallons per year — roughly 0.34 gal/h. A running toilet can waste 200 gal/h, adding up to nearly 2 million gallons over a year if unrepaired.
Converting L/s to gal/h is essential across hydraulic engineering, HVAC, water treatment, fire protection, and medicine. SI units (m³/s, L/s) are standard in science; European engineering uses m³/h; US systems use GPM and CFM; medical applications use L/min.
Quick reference: 10 L/s = 9510 gal/h. Reverse: 1 gal/h = 0.001052 L/s. Factor: 1 L/s = 951 gal/h.
All conversions use IEEE 754 double-precision arithmetic, accurate to at least 8 significant figures.
